I have a 1998 Grand Prix GTP with the digital (automatic) dual climate control system. About a year ago, the A/C stopped working. My parents left the car sit over the whole winter and all it needed when we woke it back up was a spark plug wire and a battery (I don't know if that's important info or not). Anyways, I know it needs a new compressor, but someone told me the actuator vent needed replaced. I had someone recharge the system to see if it was leaking (it is), and he put in 12 ounces of R-134a. It blew very cold on the passenger side, but no matter what I did, the driver side would only blow ambient air or heat. I'm not sure if it's just because it didn't have enough freon or the actuator vent is bad. And if the vent happens to be bad, how should I go about replacing it?
Thanks in advance!
